P'UME'.

iaeaeea.

T0 aZZ whom it may concern lie it known that l, HERBERT A. HANDY, acitizen of the United States, residing at Tulsa, in the county of Tulsaand State 01 Oklahoma, have invented a new and useful Pump, which isdescribed herein.

This invention is identical with the one for which I applied for LettersPatent on December 18, 1917, and which was allowed April 1, 1918, theapplication bearing Serial N umber 207781, and declared abandoned fornon-payment of final fee.

The main object of my invention is to furnish a means of extractingwater or other liquid from tubular wells into Which a cylinder oflimited diameter only can be inserted.

The present invention is really a late development of an invention of myown of a double action pump and for which I applied for Letters Patent,April 5, 1893, under Serial Number @79688.

The development consists chiefly in the attachment to the lower end ofthe piston of a part, comprising two ports, controlled by a valve orvalves and packing fitted closely to the main cylinder. Also theintroduction at the lower end of the main cylinder of a port, controlledby a valve, thus converting the double acting into a triple acting pump.

The entire reconstructed pump will be shown herein, the mechanism ofwhich is illustrated by the accompanying drawing which is a verticalsection thereof.

The several parts of the pump may be best described by reference to thedrawing wherein the main cylinder is indicated by the letters A B whileC D indicates an active cylinder or piston, acting reciprocally insideof the main cylinder and out side of the hollow head, E F and the feedpipe G. The main cylinder A B is supplied at the upper end with a cap,into which may be engaged the well pipe J, and to the cap is attached aguide K for the piston rod L to which is attached the stop M whichlimits the valve 1.

The numeral 1 indicates an annular valve working loosely about thepiston rod and controls port 2. The top plate of the piston isperforated plentifully to form port 2. Numeral 4 indicates a port in thetop, and 7 a port in the bottom plate of the hollow head F similar tothe one at 2, and they are controlled by valves 3 and 8 whichSpecification of Letters Patent.

are connected by rods, four in number for more simultaneous action. At10 and 15,

is placed a packing about the feed pipe.

Numeral 11 indicates a port in the lower.

end of the piston proper, and 12 a valve working loosely about the feedpipe and controlling alternately both ports 11 and 13. Numeral 17indicates a port in bottom of chamber 20 and is controlled by valve 16which in turn is limited by the stop ll attached to feed pipe. Numeral18 indicates a port and ball valve through which all water must enterthe pump. Numeral 19 indicates the space inside the piston between 6 andport 2 and 9 the space or chamber between 6 and port 11 while 20indicates the chambers in the main cylinder between the packing at 1Aand port 17. Numeral 22 indicates an uncontrolled port or open grill inthe side of the shallow chamber in which operates the valve 12, and at pis indicated a suction pipe which may be used if desired.

To explain the operation of the pump it will be noted that in thedrawing, Fig. l, the piston is shown in low position.

On the upward stroke of the piston valve 1 closes port 2 and, valve 3opening, chamber 19 is filled through port 4:. Also valve 12, whichcontrols both ports ll and 13, opens downward and, valve 8 closing port7, the water in chamber 9 is forced through port 11 and open grill 22,into the main cylinder and delivered: port 13 having been closed byvalve 12. Also valve 16 opening, chamber 20 is filled through port 17.

()n the downward stroke of the piston, valve 1 opens and, valve 3closing, the water in chamber 19 is forced through port 2 and delivered.Also valve 8 opening downward; and valve 12 closing upward, chamber 9 isfilled through the feed pipe G and hollow head F. Also valve 16 closes,while valve 12, doing double service, opens port 13 and closes port 11.Thus leaving the piston in position for the upward stroke when the waterwhich was previously in chamber 20 will be delivered. It will be notedthat the Water above piston cup 14: and the water in chamber 9 will bedelivered on the upward stroke, and that the water in. chamber 19 willbe delivered on the downward st k s th t Wh e the p n is s the feed pipeand the whole-inserted in the cylinder.

Havin -thus described the I construction and operation of. my pump, whatI claim is A'Zpurnp consisting of a-"main cylinder, having attached 'toits lower end, and ex-- tending partially through'it, a stand'pipefitted with a hollo'whead supplied with ports both on the upper andlower" sides, said ports being controlled by valves; said main with aport and said port controlled by a valve, a piston working reciprocallyinside said main cylinder and outside said hollow cylinder beingsupplied at the lower end i head and stand pipe, and fitted closelythereto by packing; said piston supplied at the upper end with a port,said port controlled by a valve, and at the lower end with two ports,with a small open chamber between, said chamber being supplied with avalve controlling said ports, and said chamber being supplied with openports in its sides, all substantially as described."
